Achieve passwords in Key


I have a bit under 300 sites/passwords stored in Key, and it's getting quite clumsy to use, especially in mobile.


Many of those websites/-services are ones that I'm not using anymore, but they don't allow removing user account or for some reason, I want to keep my account existing.


It could be great to be able to achieve those passwords so that they wouldn't appear in every view in Key.


I saw some people suggesting folders for passwords in LastPass-style. That wouldn't solve this issue, since especially in mobile, choosing login from list would be even slower with categories.
